Team Values and NormsPunctual
Each team member will be prompt and arrive at the team meetings on time. If an unexpected conflict comes up, the absent team member will notify at least one team-mate prior to the expected absence. An absent team-member should confirm that a team-mate has received their message (in person, voice mail, email, etc).
ThoroughEach team member will complete their tasks thoroughly and completely, so that the work does not have to be re-done by a peer on the team. If a member does not know how to complete a task, feels overwhelmed, or needs assistance then the member notifies peers, and seeks assistance either from a peer, the faculty guide, a faculty consultant, or another person.
AccurateEach team member completes their work accurately and in a way that can be easily checked for accuracy by peers and the faculty guide. All work is fully documented and easy to follow.
Professional and EthicalEach team member gives credit where credit is due. All work completed includes citations to appropriate literature, or sources of assistance. If a team member has gotten assistance from a publication or individual, then that assistance or guidance is fully documented in the reports prepared. Each team member is honest and trustworthy in their dealings with their peers.
Committed Each team member will contribute an equal share to the success of the project.
Demonstrates the core RIT values of SPIRIT.
EDGE™
Team Values and Norms
CompetentEach team member will perform his/her duties to the best of their ability. It is every team members job to posses any skills that are necessary for the completion of the project. If a team member does not possess a particular skill, it is that person's responsibility to learn it, even if it means going outside of his/her discipline. During the project it may be necessary to perform skills and techniques that you have not been trained for.
Adaptable22 weeks is a very tight schedule for a project of this magnitude. Each team member must be able to adapt to a rapidly changing schedule, as well as scope creep, changing requirements, and a shrinking budget. Each team member must be ready to assist other team members with their tasks in addition to performing their own role.

Issues and RisksRisk Possible Consequences
Probability of Risk (H/M/L)
Severity of Risk (H/M/L)
Overall Risk
(H/M/L)Contingency Plan
Materials are too heavy once built
Vehicle over weight limit, does not qualify for competition, vehicle may not fly
M H MReview design, look to past MAV design for support since it is under the limit
Vehicle does not survive crash test
Microcontroller and other components may be damaged during actual flight
L H MMicro controller will not be flown in plane until crash surviveability is achieved
Vehicle dimensions outside envelope
Vehicle not qualified for competition L M L
MAV team will not attend competion. Next senior design project will be used to reduce size of vehicle
Components do not fit inside plane
Vital functions (flight control) may be lost
L M MRevise design of vehicle. Search for smaller components or components that multi task
Design is too Complex
Undergrads may not be able to benefit from project. Vehicle may not be possible to build with current resources
L M LMay have to sacrifice overall performance for design simplicity
Aero and Structural project overlap
repeat tasks, both projects completing same work, information is lost, some design details may be over looked
M M M
The two projects may be combined into one project. This would reduce the risk of design overlap
Budget runs outUnable to procure necessary materials and resources
L L LAlternate sources of funding - Pizza Sale?
EDGE™
Outstanding Items:– Coordinate with aero design project and controls
design projects
– Update remaining sections on EDGE
– Pursue external funding over the summer
– Start recruiting team members
– Additional Risks (Early Stages of MSD1)
Recommendation:Merge the Structural (P09123) and Aero
